It keeps the processor cool when not overclocked but does a terrible job at keeping the processor cool when overclocking.

It's whisper quiet and does a great job of keeping things cool even at 100% CPU usage

The fan runs quiet and does a great job keeping the temperature of my Intel Core i7 low.

Does a great job of keeping a over clocked a10 cool in a mini itx build while remaining quiet.

Does its job great, i'm maxing out just above 50 degrees

The h55 quiet edition is a good cpu cooler, however, corsair's backplate is plastic and the metal screw-holes can slip making it nearly impossible to take off (eventually I had to superglue the screws to the plastic just to free my prossesor)

I'm using the H55 Quiet Edition and it has kept my CPU temps between 25-

Well Corsair might as well change the name to "Loud as a Train Edition", because it is

DISCLAIMER: I bought the H55 Quiet edition, but this should apply to all of them

The Corsair Hydro H55 Quiet Edition Liquid CPU Cooler is just what my mini computer build needed

The backplate of the cooling unit will rest on the capacitor solders on the backside of the mobo

I've purchased 5 of these coolers before and have only had one defective unit (pump failed) over the last 7 years

The unit is very quiet as long as you keep the pump under 1200 RPM.

Unit is so quiet that I often wonder if my computer is even on.

Because of the pump sounds, I expect my unit was defective and returned it.

Needed to replace my old liquid cooling system in my computer

I rather have spent the money in another cooling system.

I replace the cooling system with this Corsair on and it has been working great ever since.

Replaced the dead stock cooling system in my Alienware R4 with this unit

With my 212evo my system idled at 40c and under load got to around 70c

I replace the cooling system with this Corsair on and it has been working great ever since.

dont wasted ur money its garbage cooler dont believe in anyone here my temp over 40and one of pipe not working stay away from

But the ease of installation aside, the cooler works perfectly and is every bit as capable as the one that came stock in the Alienware.

the corsair cooler with 2 fans works great the temp stays around 32c to 45c degrees , I will be buying a bigger water cooler and bigger radiator with 2 - 240 mm fans next for a new system that I'm building

Pump stopped working and caused my 6700k to burn up, ruined my computer now have to get CPU and fans to replace this.

Dropped my 8 core AMD processor from 40 C to 24 C while idling

(Gelid Silent 12 1000) running at 500rpm, overclocked to 4.5GHz, 1.44V. Not a high performance cooler, but the pump is quiet, and the included fan isn't annoying at all

Does a great job at improving the performance of my computer

bracket).The GPU was running at 45 C idle / 91 C under load, and it was throttling while using Sapphire's cooler

The cooling performance of this is on par with the h100i.

I am happy with the purchase and got this for a pretty good sale price

I was a bit worried about purchasing this water cooler at first because of how cheap the price was

Dropped my 8 core AMD processor from 40 C to 24 C while idling

All in all, this is an excellent cooling solution that comes in at a pretty solid price

Gaming and higher OCs (400-600 Mhz on both CPUs) produce idle at ~32-35 C and ~65-68 C under gaming load

No matter the fan cooling system I used, I always hit 90 C if stressing or high OC gaming.

The intel stock cooler would reach 80 to 90 c under load.

Luckily i had a Corsair ultra quiet fan laying around that i switched it

What else can be said it's Corsair came on time love it!

Corsair link is not necessary to install either, since I know many people do not like Corsair's software

Just as easy an install as CPU fan, and the radiator fan bolted right to chassis.

Saw the U-Tube video about how to attach the retainer ring then was easy install.

Again, I've never had an issue with a Corsair cooler, and I've installed quite a few now

Terrible instructions and the install took way longer than it should have given the way the cpu cooler block was designed

Install was a little bit intimidating with having to remove the stock mounting bracket from the motherboard, but wasn't too difficult to actually do.

Easily 4.5 stars, but the USB cable travesty is the only thing that keeps me from rounding up to 5 stars

(And the older product was not very quiet, this one is really silent which is one great thing about it)

What I personally think is the most amazing thing about these coolers is that they outperform standard (and enormous) air coolers while running very quiet

This thing is also very quiet, which is where I was also going with my build up.

Holy crap, this thing makes more noise than my factory fan

First off the silver plastic bracket was not attached to the pump assembly on arrival, second the pump made a very loud clicking/rattle sound.

the thing never breaks 38 C even when it is super busy.

First, your motherboard probably relies on air flow created by the fan on the heat sink spilling over the socket and moving air around the chipset on the motherboard

Now, the flaw, and it’s not insignificant.... check your motherboard for capacitors that are inside that box created by the heat sink support holes

If you want a robust heat sink mount, I suggest you seriously consider the Noctua mounting kit if you plan to use this Corsair water cooling product

If only the heat sink could just push and twist in like the stock fans

Now, the flaw, and it’s not insignificant.... check your motherboard for capacitors that are inside that box created by the heat sink support holes

Not as great as I'd hoped...

It's not AWESOME or ground breaking, but better than the tower air cooler I had previously.

Decently cools my i7-7700K at stock speeds

I've honestly stayed away from liquid cooling systems for fear of broken pins, leaks, etc

As of yesterday this thing is a dead broken item that fails to live up to the hype

and up unless you're building a very low budget system with no heat issues and you paid less than $100 for your chip

Really easy to install and I no longer have over heating issues.

My 1080 was overheating cleaned it like 3 x still having over heating issue

Needless to say, I very impressed as I was initially concerned I would have to reduce my OC settings

Now when I encode videos, the hottest I've seen my CPU get up to is

Back plate is a cheap pliable plastic with pot-metal hex standoffs reminiscent of a $12 aftermarket air cooler from the 90s

The tubes are a bit hard to articulate in place, but patience will usually get you through that stressful installation

The fans can be a bit loud for my taste but they do move some air

Installing the bracket in the CPU block can test your patience a bit too, but you'll sort it out quickly, even with a slightly confusing manual

Otherwise it was nicely made, didn't leak a bit, seemed to move heat away efficiently, quiet

Note : if you use X99-Delluxe/3.1USB MoBo the USB connector below the pomp will not fit well between the pipes , not on top or below very hard to fit so it is not best choice to use it with this MoBo , if the connector was not right curved there will be no issue , the manual show the USB on top bit it is not

I've honestly stayed away from liquid cooling systems for fear of broken pins, leaks, etc

this is a good cooler, I've used corsair AIO's for years now, but my only complaint is that my particular cooler ended up leaking onto my system, thankfully it was a

but I'm really glad I made the switch there have been no issues with this thing no leaks

Needless to say, I very impressed as I was initially concerned I would have to reduce my OC settings

Ive heard too many horror stories ranging from "the pump broke and my CPU overheated" to "it was leaking and leaked all over my GPU"

Liquid cooler itself is fine and does its job well but the fan that came with it started to make noise after 3 weeks and ruined the whole "quiet" experience.

This new H55 model does not seem to be made as robustly as the old, and the low noise silent fan that came with this unit is anything but.

Both started out fine, but now make a super-annoying rattling noise.

However after a few months of use it started making this horrible rattling / clicking noise

About noise the H55 it is very quiet in order to give the best performance/low noise radio, about the H80i GT the SP120L fans are so much louder but you must consider 70 CFM of flow and 4,65 mmH20 of pressure, and that means power and you see clearly the results (check GPU-z screenshots), about pump noise I read some reviews here warning about pump noise, in my case with the H55 pump (1500RPM constant speed) and H80i GT (1850 RPM quiet 3000 RPM performance), so far I have not heard any noise, very quiet both pumps

The higher end coolers also have quieter / more efficient fans and beefier hoses

Don't force anything, you could damage the hoses and have water everywhere.

I like the H60 over this one, and suggest the step up if you don't mind fatter hoses.

BUT although the Prolimatech fits the 120 mm bolt holes, I had to file the fan shroud to clear the radiator hose fittings

I was not aware that this version (2013) have bulkier hoses
